A wrecking ball is hanging at rest from a crane when suddenly the cable breaks. The time it takes for the ball to fall halfway to the ground is 1.2 s. Find the time it takes for the ball to fall from rest all the way to the ground.

I WILL GIVE TONS OF POINTS AWAY TO WHOEVER ANSWERS THIS CORRECTLY

1.697s

Explanation:

We use the second equation of free fall under gravity as follows;

Since  the ball fell freely, u = 0m/s, therefore equation (1) reduces to

Given that h is the total height the ball falls through in time t seconds.

However, according to the stated problem the ball falls halfway in 1.2s, this simply implies that the ball falls through a distance of in 1.2s. Hence we can write the following, given that ;

We can now proceed to find the time t for which it falls through h = 14.112m as follows;
